Walker Products 250-24263 rear oxygen sensor for the 2004 Volkswagen R32 V6 3.2L and other vehicles reads the oxygen in the exhaust gas. It is built for its specific application and fitment position, and it gives the ECU the diagnostic feedback it expects.

• Determines the oxygen content of the exhaust gas and monitors the air-fuel ratio for combustion efficiency
• Monitors exhaust gases to help reduce pollutants
• Electrodes made of a gas-permeable platinum layer
• Measures oxygen levels so the air-fuel mixture can be fine-tuned for fuel economy
• Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gas
• Narrow-band sensor with four wires
